IMPROVEMENT IN SCHOOL-DESKS.

Specification forming part of Letters Patent No. 209,951, dated November12, 1878; application filed 4 December 11, 1876. v

rest.

It is customary to make the seat and back of school-desks and hall-seatsfrom long, narrow slats of wood. These slats, of course, spring more orless, and noise is produced by the contact of the edges of the slats.

The objects of my invention are, first, to stiffen the slats and preventnoise; second, to

- provide an adjustable foot-rest; and these objects I accomplish bymeans of a suitable wire inserted into the slats, as hereinafterdescribed, by providing the seat-standards with a series of recesses toreceive the ends of the footrest.

In the drawings, A represents a cast-iron standard for a school seat anddesk; B, the seat-arms; a, the slats which form the seat b, the slats ofthe back; 0, a steel wire, which passes through the inner slats and intothe outer slats of the seat; 0, a corresponding wire in the slats of theback.

In manufacturing, a hole is to be bored through each of the inner slatsand into each outer slat. One end of the wire is then to be insertedinto the hole in one of the outer slats, and the other slats are drivenone after another upon the wire.

For seats of the length represented a single wire for the seat and asingle wire for the back I slats.

loose or escape from the position in which they cated at suitabledistances apart.

The slats are to be secured to the standards and seat-arms in the usualmanner.

This construction strengthens the slats, keeps them securely in place,and prevents the rubbing of the edges together.

O is a foot-rest, the ends of which are supported and secured in arecess in the standards. d, in each standard and the foot-rest can belocated as may be required for the use of the pupils.

The adj ustabili ty of the rest has been proved valuable in use.

The rest 0 is secured in place by means of the screw or bolt 9 and nuth, as shown in Fig. 4.

The still rods or wires furnish a very efticient mode of strengtheningand supporting the They are noiseless, and cannot become are placed.

What I claim as new, and desire to secure by Letters Patent, is asfollows:

1. In combination with a slatted seat or back, metal rods or wiresplaced between the supports and passing through the intermediate slatsand into the boundary-slats, so as to hold the rods in place and preventthe unequal springing of the slats, substantially as specified. I

2. The standards A, provided with a series of recesses, d, incombination with the footrest 0, substantially as and for the purposespecified.
